Panic Assist making us panic even more

Panic Assist keeps sending me text messages saying that R117.50 will be debited from my account on the 2nd of July 2018. I have not authorised such a transaction and no one can help me when I call their call centre. I can reverse these debit orders but they can just change the reference number and still debit from my account. This is a serious concern...it seems that anyone can access our private information without our knowledge and consent. I am mostly disappointed with Panic Assist because there are numerous complaints about this and no one from the company is coming forward to assist.
